I watched and finished Haikyuu!! yesterday. I really liked it. It was funny and the Volleyball stuff was actually interesting for someone who knows next to nothing about it. Good character development, great pacing, and plenty of motivational moments to be had.
It got me in the mood for sports anime, so I'm not watching Kuroko no Basket. I'm on episode 9. It's not as good so far, but it's holding my interest. It's far more fast paced, with them already entering the inter-high tournament on episode 4. I'm not sure if I like that. The actual sports stuff doesn't seem as involved either, which is fine considering how unrealistic it is.
